T0 aZZ'whom it may concern:

Be it known that 1, JOHN R. Lone, a citizen of the United States;-res1d1ng at Kenmore, in the county of Summit and State of Ohio, have invented certaln new and'useful Improvements in a Vise, of which the following is a specification.

My invention perta-ins to an improvement in Vises, and particularly in vises of the type heretoforepatented by me and 'disclosed 111 my Letters Patent No. 667,152, my ob ect being to simplifythe Construction and assembly of parts and more efiectively lock the vise against rotation in the vertical and horizontal positions in which itis adapted to be placed and used uponits supporting 0st. i p Inthe annexed drawing; Fig. 1 is a vertical section longitudinally through the body of the main vise'parts, and Fig.2 is a vertical section transversely of the vise on line 22 of'Fig. 1. Fig. 3 is a horizontal section of the vise on line 3-3 of Fig. 1. Fig. 4 is a perspective view of the integral looking element and nut. Fig. 5v 1s a reduced view showing the body ofthe vise in a horizontal position on the post.

The vise comprises a body 2 having a fixed jaw 3 and an integral extension 4: at lts front side opposite a substantially square opening 5 which extends through the'body from the rear and is adapted to receive and guide the hollow extension 6 of the movable jaw 7 The operating screw 8 is housed within extension 6 and has a round enlargement 9 seated within around recess within the front side of the movable jaw, and a locking pin or screw 10 extends transversely through the front end of the jaw and rests within an annular groove 11 in enlargement 9, thereby permitting the screw to be 1 turned but preventing the screw from beingwithdrawn from its socket. The enlargement 9 however, bears against the inner end of the socket in clamping operations and the pin is not subjected to any strain at this time. The screw-threaded end of the screw passes through a screw-threaded opening in the upper end of a locking'member 12 which is mounted at its lower end upona pivot pin 14: extending transversely through the flanged sides 15,15 of body 2. The' look ing member 12 is located at the rear side of the body opposite and parallel with a round vertical bore 16 extending upwardly from the bottom of the body, and the inner .hance the locking elfectat the upper end of the post asnear thescrew. as possible.

action does not occur untilthe final clampvertical face 17 of the locking member is curved longitudinally to fit the round face of. the; supportingv post 19 of a stationary base member 18 upon which the vise is adapted-to be rotated to different working .positionsj Looking member 12 is relatively long .an'dis'pivoted at its bottom end relatively near the lower end-of body 2 to en- Thus'the more distant the pivot pin islocated" from the screwthe greater the are movementof the locking member atthe uplperendof the post and the tighter the grip on the post, and when the post and locking member are accurately/made only a slight rocking; movement of the locking member is required to effect locking- .I-lowever, this ing movement of jaw 7 upon the work. A

slight play exists between the co-acting' screw-threads and also'at. the socket end of the screw, which permits the slight rocking V movement required by the locking member and a slight loose play may also be pro vided at the pivot pin. In clamping the jaws and locking the body of the vise upon the post to prevent rotation the movable jaw is solidly supported at its front and heavier. end by the integral extension on' I .body 2' and the said jaw is also closed at its bottom where resting and sliding upon said extension. Thus in clamping the work between the jawsno tilt occurs in the movable jaw. and the work is, not disturbed or displaced from its predetermined setting, for example for a templet and the part to be operated upon.

The vise is also particularly constructed i to permitit to be supported in a rotatable horizontal position as shown in Fig. 5. Thus body 2 has round-bosses 20-20 upon opposite sides and a round bore 21 transversely of vertical bore 16 intermediate the 1 upper and lower ends thereof where locking engagement of the post may be effected by the locking member intermediate its pivot pin'and the clamping screw. To, obtain effective locking in this position on the post r the locking member is formed with a curved locking surface22 transversely of its longitudlnally curved face,see Fig. 4, and the curvature in both instances corresponds to the diameter of the post and the boresfor the "post.

on either of its sides or supported in a ver The vise may be laid horizontally tical position, and a secure locking effect is obtained on the postin each of these positions by the use of a long locking member pivoted and arranged at the rear side of the body as herein shown and described.

This result is further aided by the stable seating position of the sliclable jaw upon the immovable integral extension l.

What I claim, is:

1. A vise, comprising a body having an opening extending horizontally therethrough from front to rear and round intersecting bores extending vertically and transversely within its bottom portion and a vertical slot at its rear open to said horizontal opening and both bores, said body also having a fixed jaw at its upper end and an integral extension. at its front opposite said horizontal opening, a movable jaw having a hollow extension projecting through said horizontal opening and seated upon the integral extension of said body, an operating screw extending through the front end of said movable jaw into said hollow extension, a locking member having a screw-threaded opening at its upper end for said screw and a pivot pin at its lower end engagedwith the bottom portion of said body, said locking member occupying said vertical slot at the rear of said body and having a curved clamping'face longitudinally thereof above said pivot pin opposite the rear side of the vertical bore and also a curved clamping face transversely thereof opposite the transverse bore intermediate the pivot pin and said screw, and'a supporting base for said vise having a round post of approximately the same diameter as said bores.

2. A vise, comprising a body having a fixed aw and an integral supporting extension at its front side and a through opening rearwardly and above said extension, a slidable jaw member having a hollow extension open at its bottom approximately half its length at its rear end and seated at its closed end upon said integral extension, an operating screw rotatably mounted within said slidable member a verticallyextending locking member confined at its upper end within the rear end of said hollow extension and pivotally connected at its lower end to the rear part of said body, said locking member having direct screw-connection with said operating screw and said body having round intersecting bores extending transversely and vertically therein opposite and open to said locking member, and a support for said vise having a round post to fit within said bores and adapted to be engaged by said locking member.

In testimony whereof I afiix my signature hereto.

JOHN R. LONG.
